The 1st Workshop on Trustworthy Learning on Graphs (TrustLOG)

Colocated with the 31st ACM International Conference on Information and Knowledge Management

About

Learning on graphs is at the core of many domains, ranging from information retrieval, social network analysis to transportation and computational chemistry. Years of research in this area have developed a wealth of theories, algorithms, and open-source systems for a variety of learning tasks. State-of-the-art graph learning models have been widely deployed in various real-world applications, often delivering superior empirical performance in answering what/who questions. For example, what are the most relevant web pages with respect to a user query? Who can be grouped into the same community? What items should we recommend to best-fit user preferences? Despite the prosperous development of high-utility graph learning models, recent studies reveal that learning on graphs is not trustworthy in many aspects. For example, existing methods make decisions in a black-box manner, which hinders the end-users to understand and trust model decisions. Many commonly applied approaches are also found to be vulnerable to malicious attacks, biased against individuals from certain demographic groups, or insecure to information leakage. As such, a fundamental question largely remains nascent: how can we make learning algorithms on graphs trustworthy? To answer this question, it is crucial to propose a paradigm shift, from answering what/who to understanding how/why, e.g., how the ranking of webpages can be manipulated by the malicious link farms; why two seemingly different users are grouped into the same online community; how sensitive the recommendation results are due to the random noises or fake ratings.

There are many challenges involved in trustworthy learning on graphs, including:

  • Understanding the implications of non-IID graph data on the classic trustworthy machine learning;
  • Discovering graph-specific measurements and techniques for trustworthy learning;
  • Achieving trustworthy learning on graphs at scale;
  • Accommodating the heterogeneity of graph data;
  • Dealing with dynamically changing and/or temporal graphs.

This one-day workshop aims to bring together researchers and practitioners from different backgrounds to answer these research questions and enhance the trustworthiness of learning on graphs. The workshop will consist of contributed talks, contributed posters, invited talks and discussion panels on a wide variety of methods and applications. Work-in-progress papers, demos, and visionary papers are also welcomed. We will also include invited papers for both oral presentation and poster presentation. This workshop intends to share visions of investigating new approaches and methods at the intersection of trustworthy learning on graphs and real-world applications.

Paper Submission

Paper submissions are limited to a total of 5 pages for initial submission(up to 6 pages for final camera-ready submission), plus references or supplementary materials, and authors should only rely on the supplementary material to include minor details that do not fit in the 5-page main body. Manuscripts should be submitted in PDF format, using the ACM 2-column sigconf template. Paper reviews will be double-blind, and submissions that are not properly anonymized will be desk-rejected without review. Submitted papers will be assessed based on their novelty, technical quality, potential impact, and clarity of writing. For papers that rely heavily on empirical evaluations, the experimental methods and results should be clear, well executed, and repeatable. Authors are strongly encouraged to make data and code publicly available whenever possible. The accepted papers will be posted on the workshop website and will not be included in the CIKM proceedings. Special issues in flagship academic journals are under consideration to host the extended versions of best/selected papers in the workshop.
